Why you really can't use 'Linux' as a screen name on the Xbox 360
When the news broke about it being impossible to use Linux as a screen name on the Xbox 360 it sounded like such a Microsoft thing to do. Alas, the real reason why you can't use Linux as a screen name is much more mundane.
The news that you couldn't use, oh say, "Linux Rules" as a screen name on the Xbox 360 online gaming circuit appears to have first appeared on Xbox Scene News. After that, the story spread like wildfire as Xbox 360 users tried it for themselves. Their attempts were met by the error message "Your motto contains inappropriate language. Please try again".
